Embodiment Construction
[0024] The technical solutions in the embodiments of the present invention will be clearly and completely described below.
[0025] An automatic tuning method for stringed instruments based on a wireless sensor network. The information transmission network is constructed through the communication function of the wireless sensor network nodes, and the vibration frequency of the strings is sensed by the sensor.
[0026] After comparing with the reference frequency from the sinking point of the wireless sensor network, a feedback signal is sent out to control the string shaft on the node to perform corresponding tensioning or loosening actions.
[0027] As a preferred mode of the present invention, the specific steps of the present invention include:
[0028] Step 1: Build a wireless sensor network. The sensor is used to sense the vibration frequency of the strings. The sinking point is used to receive the string vibration frequency and reference frequency output by the sensor. T...
